I want an Imageview to expand and assume the biggest width respecting the parent viewgroups margins. The width of the parent must however behave like wrap_content when the ImageView is dynamically hidden.
Consider the following layout:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="8dp"
android:paddingRight="8dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:src="#drawable/strasse_hintergrund"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Short Text"/>
</LinearLayout>
The following images show what the layout looks like, both with a short and a long text in the textview:
I need the ImageView to always have assume width as in the second version (with the long text).
What is the best way to achieve this?
Try this :
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/strasse_hintergrund"/>
and maybe change :
android:layout_width="match_parent"
to
android:layout_width="wrap_content"
EDIT :
Here is my code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="19dp"
android:background="#color/dark"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:layout_weight="0.02">
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="7pt"
android:textColor="#color/white"/>
</android.support.v7.widget.Toolbar>
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
/>
<TextView
android:id="#+id/textView"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="10pt"/>
</LinearLayout>
Result :
Place TextView and ImageView in different LinearLayouts and place both inside a third LinearLayout OR
use match_parent instead of wrap_content for your TextView width
You can set this android:scaleType="fitXY" property for Imageview
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:src="#drawable/your_image"/>

I want to display a custom text (mainly person info) inside an image like it's shown above. How can I do it in android? For example, I have a known size of this image (it differs from device to device) and want to display it with the different text size inside it in the special place.
You can use, for example, RelativeLayout.
Make your ImageView be match_parent and use some container for your text lines in bottom of parent RelativeLayout.
Example:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:scaleType="fitXY"
app:srcCompat="#drawable/ic_launcher_background"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:padding="20dp"
android:background="#92fffaaa"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="200dp">
<TextView
android:textSize="20sp"
android:text="Some test text"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</RelativeLayout>
Result:
Try this (adjust dimensions as your requirement)
<RelativeLayout
android:layout_width="200dp"
android:layout_height="150dp">
<ImageView
android:scaleType="centerCrop"
android:src="#drawable/your_image"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:background="#64000000"
android:padding="8dp"
android:gravity="center_vertical"
android:orientation="vertical"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:text="Title"
android:textColor="#ffffff"
android:textSize="16sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:text="Sub Title"
android:textColor="#ffffff"
android:textSize="14sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
I've done something similar previously.
Use Framelayout.
Add ImageView in frame layout with match_parent constraints.
Add LinearLayout having background="#80000000" and layout_gravity="center" in FrameLayout which contains your two TextViews.
Let me know in case this does not work.
I'm developing an app and I need to fill the entire screen with a background, this view contains a scrollview. The problem is that the background is not covering the entire screen, it has a white stripe at the bottom, like the image below.
I have already tried many options of scaleType, like fitXY, centerInside, etc. none of them worked out.
My XML is below.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_height="match_parent">

android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:src="#drawable/signup_background" />

android:layout_width="match_parent"
android:layout_height="match_parent"

Can anyone help me? Thanks.
I think that you have to give background to ConstraintLayout with width wrap_content. also set your height for both ScrollView and ConstraintLayout wrap_content.
In constraint layout you have to specify constraint. You don't have specified constraint in ImageView
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:src="#drawable/signup_background" />
Replace it with
<ImageView
android:layout_width="0dp"
android:layout_height="0dp"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:src="#drawable/signup_background"
card_view:layout_constraintBottom_toBottomOf="parent"
card_view:layout_constraintLeft_toLeftOf="parent"
card_view:layout_constraintRight_toRightOf="parent"
card_view:layout_constraintTop_toTopOf="parent" />
Try to use RelativeLayout instead of ConstraintLayout in your xml. Relative Layout is best for overlapping two elements of xml.
I got the answer, what I needed to do was to put a RelativeLayout as parent of the ScrollView, like below.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/signup_background"
android:orientation="vertical"
android:padding="40dp">
...
</LinearLayout>
</ScrollView>
</RelativeLayout>
This is the Layout of a Fragment(attach on the main Activity):
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.carbos.user.nameapp.Class"
android:orientation="vertical">
<!-- TODO: Update blank fragment layout -->
<TextView
style="#style/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/title"
android:layout_alignParentTop="true"/>
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="0dp"
android:layout_below="#id/title"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/desc"
android:layout_below="#id/image"/>
</RelativeLayout>
But the distance between TextView and ImageView doesn't 0dp and there isn't #id/desc.
This is the output(the image and title is for example) :
This is the image in Drawable:
How can i set the distance between TextView and ImageView( and TextView of #id/desc)? I tried with LinearLayout, but it doesn't work
My guess is that there is no distance between textview and imageview. The gap you see is the white space in the image.
To check this theory, try setting imageview background instead of source.
You should try changing the ScaleType of the ImageView to something else. Probably CenterCrop. For more information see: http://developer.android.com/reference/android/widget/ImageView.ScaleType.html
Try this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.carbos.user.nameapp.Class"
android:orientation="vertical">
<!-- TODO: Update blank fragment layout -->
<TextView
style="#style/title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/title"
android:layout_alignParentTop="true"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="200dip">
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_below="#id/title"/>
</RelativeLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/desc"
android:layout_below="#id/image"/>
</RelativeLayout>
I would like to make an ImageView overlay another ImageView like this; only half of the circle green is overlaying the image:
I have tried using RelativeLayout and put both ImageView inside. Then I overlay the circle over the image by using android:layout_alignBottom. It did overlay the but I have no idea how to set the offset so that only half of the circle is overlaying the base image.
EDIT:
Sorry, here is my layout xml code
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="32sp" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/image_view_product"
android:layout_centerHorizontal="true"
android:background="#drawable/image_view_circle"
android:src="#drawable/ic_circle" />
</RelativeLayout>
I get lots of upvote for this answer.So i try to improve that answer. May be this is the better way to do that compare to other two, because this solution doesn't required to fix the layout or divide screen in equal part so may be this is better to do that.

Alternate way Try this

<LinearLayout
android:layout_width="match_parent"

android:layout_weight="1">
</LinearLayout>
// this is your bottom layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</LinearLayout>
</LinearLayout>
// This is the imageview which overlay the first LinearLayout
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/success"
android:adjustViewBounds="true"
android:layout_gravity="center"/>
</FrameLayout>
its look like this
found one more solution for that (Edit)
if your big image size is fixed height you can try this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:id="#+id/layoutTop"
android:background="#color/red_error"
android:layout_width="match_parent"
android:layout_height="200dp" >
</RelativeLayout>
<RelativeLayout
android:id="#+id/layoutBottom"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_alignParentBottom="true"
android:layout_below="#id/layoutTop" >
</RelativeLayout>
<ImageView
android:id="#+id/overlapImage"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_above="#id/layoutBottom"
android:layout_centerHorizontal="true"
android:layout_marginBottom="-20dp"
android:adjustViewBounds="true"
android:src="#drawable/testimage" />
</RelativeLayout>
Refernce :- Android: Placing ImageView on overlap between layouts
Hope this will help.Good Luck
Try out this way:
Just change layout_width and layout_height according to your need.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<View
android:id="#+id/viewOne"
android:layout_width="match_parent"
android:layout_height="200dp"
android:background="#126989" />
<View
android:id="#+id/viewTwo"
android:layout_width="match_parent"
android:layout_height="70dp"
android:layout_below="#+id/viewOne"
android:background="#547866" />
<View
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_alignBottom="#+id/viewTwo"
android:layout_centerHorizontal="true"
android:background="#ff7800"
android:layout_marginBottom="35dp" />
</RelativeLayout>
It will look like this:
I would recommend Constraintlayout as it gives excellent control over the positioning of individual view items. Sample based on your example below
<android.support.constraint.ConstraintLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/parentLayout">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product"/>
<View
android:layout_width="50dp"
android:layout_height="50dp"
app:layout_constraintTop_toBottomOf="#+id/image_view_product"/>
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_alignBottom="#id/image_view_product"
android:layout_centerHorizontal="true"
android:background="#drawable/circle"
android:src="#drawable/ic_add_circle_green_24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"/>
</android.support.constraint.ConstraintLayout>
Use layout_marginTop = -20dp ( Half of your image size ). It will go up.
android:layout_marginTop="-20dp"
put both the image in Relative layout
first define the image you want to put behind the green circle
than define the green circle as
android:layout_alignBottom="#+id/Image1"
Than adjust the position by giving margin to the green circle image.
I recommend you to use a framelayout with these two images.
with the refresh imageview at the bottom and the table fan at the top.
Note : As the framelayout behaves like a stack, the item at the bottom will appear at the top.
And do the set the gravity of the refresh icon to be bottom|center to make it look this way.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:src="#drawable/ic_fan"
android:scaleType="centerCrop"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
<ImageView
android:src="#drawable/ic_refresh"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:gravity="center|bottom"/>
</FrameLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="32sp" >
<ImageView
android:id="#+id/ivBackground"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_marginTop="-20dp"
android:layout_below="#+id/ivBackground"
android:layout_centerHorizontal="true"
android:background="#drawable/image_view_circle"
android:src="#drawable/ic_circle" />
I think this should help you i have edited your code and made changes as below
- I change circle imageview height to 40dp and then i give margin top -20 dp so that image will overlay half as you need on background image.
I did not run this code so if you face any issues just let me know i hope this works well for you..

i'd like to have this effect for every text:
but if I try to add a longer text, my text will be cut off:
I see that lot of people have this problem, but I haven't found anything helpful.
How to fix this problem?
Your TextView width is match_parent which means your TextView will have the same width as your parent LinearLayout. Your LinearLayout have a narrow width so your TextView will have a narrow width too.
EDIT: You have to think of your TextView as if he is on the same orientation as your parent. If he had the same orientation you would have the TextView with a narrow width.
Change the following attribute of TextView
android:layout_height="wrap_content"
to
android:layout_height="match_parent"
so that it stretch down to the full parent height.
